New coach Bill O'Brien made it clear two weeks ago that the Houston Texans have a "wide open" competition at quarterback.

Now he's hinting that one of his four signal-callers won't make it through training camp.

"Anytime you have four, I don't think it's easy to divide the reps," O'Brien said Monday. "I think you can really get three guys reps in a practice, which is basically what we've been doing, and I know that's probably not the easiest thing for those guys.

"We haven't really talked about the roster yet as it relates to training camp. ... It's a very competitive situation."
